API & Integration Testing
before hidden dependencies break revenue

Endpoint contracts, payload assumptions, version boundaries, and downstream expectations across critical user journeys.

Breakpoints by customer impact, revenue exposure, and release likelihood so your team knows what to protect first.

A focused integration-risk map that turns vague dependency fear into an actionable testing plan.

Authentication, authorization, role changes, token refresh behavior, rate-limit handling, and error-code contracts end-to-end.

Non-happy paths where retries, fallback logic, and partial responses create silent data or workflow corruption.

Integration flows that fail predictably and recover safely instead of breaking trust in production.

Timeouts, latency spikes, malformed payloads, upstream outages, downstream throttling, and queue backpressure.

Which service, policy, or retry behavior amplifies failure so fixes are targeted by impact, not guesswork.

Evidence-backed resilience limits and a prioritized hardening list tied to real customer risk.

Integration suites, contract assertions, failure-mode checks, and release criteria directly in your CI and delivery process.

Operating standards and ownership routines so product and engineering can run and evolve the gates independently.

A client-owned integration confidence system that compounds with each release instead of resetting.
